Avis put off writing her term paper until three days before it was due. "It's not that big of a deal. I can whip it out in a couple of hours," she thought. As it turned out, this was not the case. She averaged two hours a night sleep as she struggled to write the paper and turn it in on the due date. Once the project was submitted, she returned to her dorm room and collapsed into a deep sleep. Research has shown that she will:

A. sleep fitfully for several nights.
B. spend more time in REM sleep than she normally does.
C. suffer a brief period of short term memory loss as a result of the sleep deprivation.
D. suffer an extreme but temporary dip in her immune system.

B. spend more time in REM sleep than she normally does

Right.

Given the scenario described, it is likely that Avis will experience sleep deprivation as a result of working on her term paper only a few hours a night for three consecutive nights. Sleep deprivation can have various effects on the body and mind. In response to this situation, the most likely outcome for Avis based on scientific research would be:

B. Avis will spend more time in REM sleep than she normally does.

REM (Rapid Eye Movement) sleep is a stage of sleep characterized by rapid eye movement, vivid dreams, and increased brain activity. It is during REM sleep that the brain processes and consolidates memories. When someone is experiencing sleep deprivation, their body will prioritize REM sleep to compensate for the lack of it. As a result, during the first few nights of recovery sleep, they tend to have an increased amount of REM sleep.

It is important to note that while B is the most plausible answer based on the given information, it is always essential to consider individual differences and potential variations in response to sleep deprivation. The effects can vary from person to person.
